[0001] The utility model relates to the technical field of plastic granulation, in particular to a plastic granule mixer for granulation. Background Art

[0002] Plastic granulation includes the processes of melting, extruding, cutting, cooling, etc. of plastic raw materials. Plastic raw materials are generally one type of plastic particles or a mixture of multiple types of plastic particles. They must be fully stirred before entering the granulation device. In addition to stirring the agglomerated plastic particles or fully mixing multiple types of plastic particles, it is also necessary to prevent the plastic particles from mixing with water, which will lead to process defects in the produced pellets. Therefore, the use of professional plastic particle mixers is indispensable.
